CHIROPRACTORS TABLE.

Application ,filed April 6,

To aZZ whom it may concern."

Be it known that we, J-nssn RAY WEAVER and LEROY E. FULLER, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Chiropractors Table, of which the following is a specification.

Our invention relates to improvements in tables or supports used in connection with the practice of anatomical adjustments and is particularly adapted for use by chiropractors and others practicing healing methods wherein spinal adjustments, manipulations and the like are performed.

One of the objects of our invention is to provide a table for supporting the patient in a position wherein the greatest relaXations in the spinal region may be obtained.

Another object of our invention is to provide a table having the above characteristics, which maybe readily adjustable to patients of different sizes.

For the purpose of disclosing our invention we have illustrated one embodiment thereof in the accompanying drawings in which 4 Fig. 1 is a side elevation of a table embodying our invention; a V

Fig. 2 is a plan viewthereof;

Fig. 3 is a side elevation partly in section with the parts adjusted to difierent position than that illustrated in Fig.1;

Fig. 4. is a sectional view taken on the line H of Fig. 2;

Fig. 5 is a detail view showing means of obtaining one adjustment of the table, and

Fig. 6 is a detail section taken on the line 6-6 of Fig. 3. I

The table comprises a relatively stationary chest supporting portion, 1 and head supporting portion 2 and a longitudinally movable hip and leg supporting portion 3. These parts are all mounted upon a base 1 which comprises a frame formed of the two side channels 5 which at each end are connected together by cross members in the form of angle irons 6. At the four corners of the base we provide suitable supporting legs/7. The chest and head supporting portions are relatively stationary but vertically ,adjustableand to this end they are mounted 'on'a-vertically adjustable supporting frame 8 which at its rearend is provided with a pair of rearwardly extending arms 9 supporting a rocker shaft 10 on which-the chest 1923. Serial ,No. 680,207.

supporting portion 1 is mounted, suitable coil springs being interposed between the arms and the rear bottom of the chest sup porting portion 1 to maintain this portion in a substantially horizontal position and at the same time permit this portion of the table to rock to adjust itself to the chest of the patient when resting thereon. The head supporting part comprises a pair of spaced-apart pads 11 hinged at their rear end to the rear cross bar ofthe frame '8 and 7 provided at their front ends with rack bars 12, the teeth of which are adapted :to engage with the front cross member of the frame 8 and hold the front end of the head-supporting member in different angular adjustments. A'releasing latch 13 is provided, by which, the rack bars may be disengaged from the cross member to permit the raising and lowering of the front ends of the head-supporting members. It will be noted that the frame 8 inclines downwardly from the rear toward the front so that the front ends of the head supporting pads may not only be raised abovethe horizontal plane.

of the pads, but lowered beneath this plane.

telescope upon posts '17 extending upwardly from cross members 18 secured'to the'two side channels 5. The frame'8 is provided with a screw 19 which operates in a nut 20 supported in a'base 21 secured on a cross member'22 extending between the two side members 5. This nut has a bevel gear drive 23 from a shaft- 24: which in turn is driven by a chain 25 froma stub shaft 26 operated by a hand wheel "27 The hip and'leg supporting pad islongitudinally slidable relatively to the chest and head supporting pads, and to permitthis movement we provide in-the channelled side members 5 at suitable intervals, a plurality of rollers 28 on which is adapted to slide a-platform '29. 'Thisplatform comprises a pair of sidean gle irons connectedtogether by a bottom pan 30 which is secured to the under side of the horizontal portion 31 of the irons by suitable track straps 31 This structure as a whole, rests and slides upon the rollers 28. The hip supporting portion of the table has pivotally secured at its under side four hollow tubular legs 32 which telescope upon supporting posts 33 in turn pivoted-at their lower ends to the vertical members 34 of the side members of the platform. The legs 32 at their lower ends are braced by hollow brace members 35 in which are arranged sliding bolts 36 adapted to take into openings 37 in the posts 33 to permit of a vertical adjustment of the hip supporting portion of the table. In order to maintain the posts 33 in their elevated or vertical position, the bottoms of the two forward posts are adapted, when raised to the vertical, to snap into openings 38 in the free ends of pair of springs 38 secured to the under sideof the pan 30 and for disengaging these springsv from posts we provide a presser button 39 extending through the pan and connected at its lower end to a cross bar 40 which in turn is connected to the two springs 38 With the posts folded to a substantially horizontal position, the hip supporting portion, as seen in Fig. 1, is maintained at its lowermost level so that the patient may assume a kneeling position. In order to adjust this portion of the table to persons having thighs of different lengths, a pair of racks 41 are secured at each side of the pan 30 which are adapted to be engaged by a cross bar 42 at the ends of a pair of brace bars 43 pivoted at 44 to the rear legs 32.

The table is longitudinally adjusted to the chest support by an endless sprocket chain 45 which is secured by means of the bolts 46 to the under side of the pan 30. At its rear end this sprocket passes over a roller 47 mounted upon a shaft 48 journaled in a support 49 secured to the rear cross bar 6. The forward portion of the chain passes beneath a pair of rollers 50 and 51 mounted at the forward end of the base and then passes over a driving sprocket 52 mounted on a shaft 53 supported in a pair of bearing members 54. This shaft is preferably hollow and is operated by means of a pair of hand wheels 55 mounted at each end of the shaft. The hollow shaft has extendingtherethrough, a sliding rod 56 which is pinned to a clutch member 57 slidably mounted upon the shaft and provided with a series of clutch openings 58 arranged to receive a clutch pin 59 mounted in one of the bearing members 54 so that when the clutch is engaged, the sliding platform on which the hip supporting table is mounted, is looked against movement.

In normal operation, the hip supporting portion 3 of the table is in its lowered position with the patient kneeling thereon resting his chest upon the chest-supporting portion 1 and his head upon the head-supporting portion 2. The chest-supporting and head-supporting portions of the table are then adjusted to the proper height and the thigh supporting portion of the table moved to its extreme forward position. This gives the greatest relaxation to the upper portion of the spine and after the practitioner has adjusted this portion of the spine, he may then adjust the hip supporting portion of the table to throw the knees rearwardly to vary the inclination of the thighs, whereby the maximum relaxation will be obtained at the intermediate portion of the spine'and by sliding the hip supporting portion of the table. further to the rear, the inclination of the thighs may be varied to a greater extent so as to give the greatest relaxation to the lower portion of the spine.

Tn positioning the patient to obtain the best results, it is desirable that these positions for the next treatment be the same and to this end we provide a series of scales whereby the table may be adjusted for the patient, to enable the practitioner to obtain the same position for the same patient. The hip supporting portion of the table is prorided at one point with a divided pad 60 which corresponds to the zero point on the scale 61 on the base. This scale has cooperating with it, a pointer 62 moving with the sliding platform, to indicate the distance in inches of the different positions of adjustients of the thigh supporting portion of the table from the chest supporting portion. One of the rear legs 16 of the frame 8 is provided with a scale 63 cooperating with a pointer 64 to indicate the height of the chest and head supporting member 1 and 2, and the head supporting member is provided with a gage bar 65 having a pointer 66 cooperating with a scale 67 to indicate the exact position of the patient on the chest supporting portion 1 of the table.

It is sometimes desirable to operate upon the patient lying in full length and in this event the hip supporting portion 3 is raised to form a continuation in line of the head and chest supporting portions 1 and 2 and in order to resiliently support the abdomen of the patient we provide an abdominal support 68 which is mounted on a plurality of coil springs 69 connected at the points'70 and 71 respectively, to the hip supporting portion of the table and the head supporting portion.

We claim as our invention:

1. A table of the character described comprising; in combination, a frame including a pair of track members supported relatively close to the floor chest supporting pad mounted at one end of the frame and a hip supporting pad arranged to be positioned in a plane lower than the chest supporting pad to permit the patient to kneel thereon with his chest resting 011 the chest supporting pad, said hip supporting pad being longitudinally adjustable on said tracks relatively to the chest supporting pad and said chest supporting pad being vertically adjustable.
